Yes and also Hana Mandlinkova, form the 80's czech tennis revolution, ( not at liberty to discuss or reply to these accounts, pls don't ask): I know for an actual fact that they beat the crap out of their players so bad, intimidating them and slapping and beating them violently after loosing matches...no wonder they were so good!
talk about "made to win" sorry bad pun

that was a terrific frame !!!! Ken Rosewall used it also for a long time actually saw him play Mal Anderson in a seniors event ; Anderson used the Dunlop 200G.
